Our solar system is one of over 500 known solar systems in the entire Milky Way galaxy. 00:00:00
The solar system came into being about 4.5 billion years ago when a cloud of interstellar gas and dust collapsed, 00:00:10
resulting in a solar nebula, a swirling disk of material that collided to form the solar system. 00:00:18
The solar system is located in the Milky Way's Orion star cluster. 00:00:26
Only 15% of stars in the galaxy host planetary systems, and one of those stars is our own sun. 00:00:30
Revolving around the sun are eight planets. 00:00:40
The planets are divided into two categories based on their composition, terrestrial and jovian. 00:00:43
Terrestrial planets, including Mercury, Venus, Earth, and Mars, are primarily made of rocky material. 00:00:49
Their surfaces are solid, they don't have ring systems, they have very few or no 00:00:55
moons, and they are relatively small. The smallest and closest to the Sun is 00:01:00
Mercury which has the shortest orbit in the solar system at about three Earth 00:01:07
months. Venus is the hottest planet with temperatures of up to 867 degrees 00:01:11
Fahrenheit due to an atmosphere of carbon dioxide and extensive lava flows. 00:01:18
Next to this world of fire is a world of water, Earth. 00:01:23
The water systems on this planet help create the only known environment in the universe 00:01:28
capable of sustaining life. 00:01:32
The last of the terrestrial planets, Mars, might have also supported life about 3.7 billion 00:01:36
years ago when the planet had a watery surface and moist atmosphere. 00:01:42
Beyond the four terrestrial planets of the inner solar system lie the Jovian planets 00:01:48
of the outer solar system. 00:01:53
The Jovian planets include gas giants Jupiter and Saturn, and ice giants Uranus and Neptune. 00:01:55
The gas giants are predominantly made of helium and hydrogen, and the ice giants also contain 00:02:01
rock, ice, and a liquid mixture of water, methane, and ammonia. 00:02:07
All four Jovian planets have multiple moons, sport ring systems, have no solid surface, 00:02:12
and are immense. 00:02:18
The largest Jovian is also the largest planet in the solar system, Jupiter. 00:02:20
Nearby is Saturn, the solar system's second largest planet. 00:02:26
Its signature rings are wide enough to fit between Earth and the moon, but are barely 00:02:31
a kilometer thick. 00:02:36
Past Saturn are the ice giants Uranus and Neptune. 00:02:40
The slightly bigger of these ice giants, Uranus, is famous for rotating on its side. 00:02:43
Next to Uranus is Neptune, the outermost planet in the solar system and also one of the coldest. 00:02:50
Orbiting the terrestrial planets is the asteroid belt, a flat disk of rocky objects full of 00:02:57
remnants from the solar system's formation, from microscopic dust particles to the largest 00:03:02
known object, the dwarf planet Ceres. 00:03:08
Another disk of space debris lies much further out and orbits the Jovian planets, the icy 00:03:12
Kuiper Belt. 00:03:18
Apart from asteroids, the Kuiper Belt is also home to dwarf planets such as Pluto and is 00:03:20
the birthplace of many comets. 00:03:25
Beyond the Kuiper Belt is the Oort Cloud, a vast, spherical collection of icy debris. 00:03:28
It is considered the edge of the solar system since that is where the gravitational and 00:03:33
physical influences of the Sun end. 00:03:38
Our solar system's particular configuration of planets and other celestial objects, all 00:03:42
revolving around a life-giving star make it a special place to call home. 00:03:47
